REGISTER AND VENTILATOR.

Application filed. February This invention relates to registers and tionof the valve operating means.

Among the chief objects of the invention are :first, to providean-operating handle forthe valve that will lie substantially flush withor below the face of the .register when the valve is closed, whereby thepacking and transportation of a number of such registers is greatlyfacilitated in that such devices may be very closely packed, one uponanother, without danger of injury to the valve operating handle.- Again,the construction of the handle is such that it will operate the valvewhether it is pivoted adjacent its long edge or its short edge. Theseand other objects and advantages will appear to any one skilled in theart from a reading oft-h following description:

In the drawings Fig. 1 is a front elevation of a register or ventilatorembodying the invention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 3+3 of Fig. 2;

Fig. 4 is a section similar to the section shown in Fig. 2 but showingthe valve axis reversed so that the valve will swing at right angles tothe axis indicated in Fig. 2.

1 represents a perforated face plate, the cross-bars between theperforations being preferably corrugated. The edge of the face platearound the perforated portion is depressed to provide a set back borderportion 2, forming in effect a reinforcing rectangular frame- 3represents the valve provided to open and close the air passages throughthe face plate. 4 is a separate rectangular frame, which may be providedat the back of the perforated portion of the face plate and held theretoin any desired manner as by means of fastening screws 5-5. Ordinarily,the valve is pivoted at one edge to swing in the rectangular frame 4. InFigs. 2 and 3 the pivotal construction is such that the valve may beswung on its long edge, whereas in Fig. i the axis is shifted so thatthe valve will swing on its short edge. 6 represents one of the pivotpins for the valve and this may be engaged with the long edge or may beshifted to engage with the shorter edge of the valve according to theposition that the register is to 10, 1926.

occupy on the wall. This idea of shiftable valve axis is Well known inthe art and involves no part of this invention, although I have referredto it herein because my improved valve operating means is so designedthat 1tv will operate the valve equally well whether the latter ispivoted on its long edge or its short edge.

I will now proceed to describe the Valve operating means. 7 represents aflange mounted at the front of the valve 3 near one corner and securedthereto in any suitable manner as by spot welding. 7 is a longitudinal.slot in the flange 7. The operating member is in the form of a crank,the axle portion of which is indicated at ,8. At the outer end oftheaxle is an operating handle arranged at right angles thereto, while atthe inner end of the axle is a lever 10, also at right angles thereto.The lever 10 has an offset 11 which enters the slot 7. Movement of thehandle 9 is transmittedthrough the axle 8, lever 10, and offset 11 tothe valve 3 to cause it to swing to its closed, or its open, posit on.To frictionally hold it in any pos1tion,.j provide an exceedingly Simpleand effective construction as follows:

The axle portion 8 is preferably deeply seated in one of thecorrugations at the back of the face plate 1, close to one corner thereof (see Fig. 3). 12 is a clamping plate held by a clamping screw 18. Oneend of the clamping plate 12 overstands the axle 8. The screw 13 isaccessible at the front of the register so that by turning the same, thepressure of the clamping plate on the axle may be varied to furnish thedesired frictional tension to properly hold the valve. By reference tothe drawing it will be apparent that the operating means will makeoperative engagement with the flange 7 to operate the valve 3 whether ornot the latter is hinged to swing on one of its longer edges or on oneof its shorter edges. This of course is of great benefit and advantage.

I claim:

1. In a register, a perforated face plate, a set back border extendingaround the same, a valve, means for pivoting said valve adjacent to theback of the face plate to swing on either of a plurality of axes, meansfor operating said valve comprising an axle pivotally mounted on theback of the face plate and projecting through a. side of the set backborder adjacent to one corner thereof, a handle on the outer end of saidvalve arranged in one operative position to stand substantially parallelwith the border and back of ,the plane of the outer faceof theperforated faceplate and'wholly within the field of said set back borderextending around the same, a valve, means for pivoting said valveadjacent to the back of the face plate to swing oneither of a pluralityof axes, means for 'operating said valve comprising an axle piv- 'otallymounted on the back of the face plate and projecting through a side ofthe set back border adjacent to one corner thereof "a handle on theouter end of said valve arranged in one operative position to standsubstantially parallel with the border and back of the plane of theouter face of the perforated face plate and wholly within the field ofsaid border, means of connection between the other end of the axle andsaid valve, whereby motion of the axle will be transmitted to the valveto operate on either of the pivotal axes of the latter, a friction clampengaging said axle, and an adjusting screw therefor, the head of saidscrew being accessible at the front of said perforated face plate foroperation.

3. In a register, a perforated face plate, a setback border extendingaround the same, a valve pivoted at one edge adjacent tothe 7 and whollywithin the field of said border,

an angular crank at the inner end of said axle, and a sliding connectlonbetween said 'crank and said valve adjacent to one corner of thelatter.

4. In a register, a perforated face plate, a

set back border extending around the same,

a valve pivoted at one edge adjacent to the back of the face plate,ope-rating means to swing said valve comprising an axle pivot- A allymounted on the back of the face plate at one corner thereof, the outerend of the axle projecting through the side of the set back border, ahandle at the outer end of said axle arranged at substantially rightangles thereto and arranged in one position to lie close to the borderand substantially back of the plane of the outer face of the face plateand wholly within the field of said border, an angular crank'at theinner end of said axle, a sliding connection betWeen' said crank andsaid valve adjacent to one corner of the latter, the pivot for the valvebeing shiftable from one edge of said valve to another edge thereof atsubstantially right 7 angles to the first.
